SPECIFICATION forming part of Letters Patent No. 651,404, dated June 12,1900.

- Application filed March 12, 1900. Serial No. 8,302. (No model.)

To [LZZ whom it may concern:

Be it known that I, FRANK THEODORE WIL- LIAMS, a citizen of the UnitedStates, residing at Meriden, county of New Haven, State of Connecticut,have invented certain new and useful Improvements in Lamp -Burners, ofwhich the following is a full, clear, and exact description.

My invention relates to lamps, particularly of the centraldraft type;and the object is to improve the construction thereof.

Figure 1 is a side elevation, partly in section, of my device. Fig. 2 isa similar View of the parts in a different position.

In the preferred form of my invent-ion shown in the drawings, 1represents a lamp-fountof the central-draft type.

2 is an outer wick-tube, and 3 is an inner wick-tube. 4 is a wickmovable between said wick-tubes.

5 is a spreader-cone, which cone maybe conical or not, as is well knownin this art, said spreader-cone being movable up and down in the mannerhereinafter described. 6 is a wick-guard surrounding said spreader, butindependent thereof, and extending out over the wick and restingthereon. The guard 6 has a depending tubular portion 7, which preferablyfits inside of the inner wick-tube 3. This guard 6 is located at theupper end of the tubular portion 7. By this word at I do not mean thatthe guard must necessarily be at the uppermost point of the tubularportion, because that is obviously unnecessary, as the same might belocated in other positions on the tubular portion, but by such word Imean to distinguish the location of the guard near the upper end fromthe location of the guard near the lower end. This tubular portion '7 ispreferably provided with suitable perforations extending around the sameat intervals below and near guard 6. The spreader-cone is supportedwithin the tubular portion preferably by an inturned flange S on thelatter. The spreader-cone may have suitable flanges 9 and 10 toward theupper portion thereof. There is a space 6 between the tubular portion 7and the spreader when both have been raised by the Wick for the passageof vapor to the base of the flame when the wick is turned low. Thisspace may, I

have found, be very slight, and if the cone merely fits loosely withinthe tubular portion this advantage will be attained, but to a lessextent.

11 is a stationary rod which passes through a hole in the top of thespreader and carries at its upper end a removable stop 12.

13 is a wick-lift which may be connected in the well-known manner to thewick, so as to permit the latter to be raised or lowered, as desired.The raising of the wick will correspondinglyraise the flange 6 and thetubular portion 7, and through this means the spreader 5 will also beraised until itis checked by the stop 12, the position of which may beregulated as desired, so as to limit the upward excursion of saidspreader, guard, and wick. In this way it may be ascertained in advanceat just what position the Wick shouldbe stopped in order to burn withthe greatest efficiency. As before stated, the flange 6 overstands thewick, so that in addition to causing the flame to be formed at the sideof the wick and not directly on top the said guard may also act as anextinguisher when the wick is lowered by closing the space between thewick-tubes.

Inasmuch as the spreader will rise and fall with the tube 7, theair-supply is out off to the proper degree when the lamp is turned low.Practice has demonstrated that the perforations between the guard andthe spreader become foul and are difficult to clean. Consequently themaking of the said parts separable and independent for cleansingpurposes is a feature of advantage.

It will be obvious that many changes may be made in the constructionherein disclosed without departing from the spirit of my invention, andI do not limit myself to the particular form shown.

What I claim is- 1. In a central-draft burner in combination, aninnerand an outer Wick-tube between which is a space in which a wick maybe moved, a vertically-movable tubular portion having anoutwardly-extending guard at its upper end adapted to rest on and bemoved by the Wick, said tubular portion being perforated below and nearsaid guard, and a perforated air-cone supported within and by saidtubular portion and removable therefrom, there being a space for thepassage of vapor between said spreader-cone and tubular portion whenboth are raised by said wick.

2. In a central-draft burner in combination, an inner and an outerwick-tube between which is a space in which a wick may move, avertically-movable tubular portion having an outwardly-extending guardat its upper end adapted to rest on and be moved by the Wick and toclose the space between said tubes and operate to extinguish the flame,said tubular portion being perforated below and near said guard, and aninwardly-directed flange on FRANK THEODORE \VILLTAMS.
